The Ultimate Guide to Testing and Inspection of Plate Rolling Machines
In the world of metalworking, plate rolling machines play a crucial role in shaping and processing various metals into desired forms and dimensions. With the increasing demand for precision and quality in these products, it is essential to ensure that plate rolling machines are properly tested and inspected before they are put into operation. In this blog post, we will delve into the world of plate rolling machine testing and inspection, highlighting the importance of each step and providing valuable insights on how to conduct these tests to ensure the highest level of quality and precision.
General Requirements
Before embarking on the testing and inspection process, it is crucial to ensure that the plate rolling machine is properly installed and adjusted. According to the guidelines laid out in the industry standards, the installation level of the machine must be adjusted before the test, and the installation level must not be greater than 0.2/1000 in the longitudinal and transversal directions. Additionally, measures must be taken to prevent any adjustments to the mechanisms and parts that affect the performance and precision of the machine during the test. The test must also be carried out on the complete machine after it has been assembled.
Appearance
The appearance quality of the plate rolling machine is also an essential aspect to be considered during the testing and inspection process. As per the guidelines, the appearance of the machine must comply with the provisions of 3.9. This includes ensuring that the machine is free from any defects, rust, or corrosion, and that all components are properly maintained and aligned.
Accessories and Spare Parts
The random accessories and spare parts of the plate rolling machine must also comply with the provisions of 3.2.12. This includes ensuring that all hardware and software components are of high quality and meet the required specifications, and that all electrical and electronic components are properly installed and tested.
Size Parameters and Inspection
The size parameters and inspection of the plate rolling machine are critical to ensure that the machine is properly configured and functioning as intended. As per the guidelines, the parameters and sizes of the plate rolling machine must comply with the provisions of relevant product drawings and technical documents.
Quality of Treatment and Assembly
The quality of treatment and assembly of the plate rolling machine is also a vital aspect to be considered during the testing and inspection process. According to the guidelines, the quality of treatment of the inspection plate of the parts of the rolling machine must comply with the provisions of product drawings and technical documents. Similarly, the quality of the assembly of the plate rolling machine must comply with the provisions of 3.5.
Security and Protection
The plate rolling machine must also have reliable safety protection devices and must comply with the relevant provisions in GB17120. This includes ensuring that all guards, protective barriers, and safety features are properly installed and functioning as intended.
Air Operating Test
The air operating test is another crucial aspect of the testing and inspection process. According to the guidelines, the continuous air operating time of the winding machine of the plate should not generally be less than 4 hours, during which the continuous operating time of the main transmission must not be less than 2 hours, the single operating time of the main transmission must not be less than 1 hour, and the operating time of the auxiliary transmission must not be less than 1 hour.
Temperature Elevation and Unique Load Test
The temperature elevation and unique load test is also an important part of the testing and inspection process. According to the guidelines, the increase in the temperature of each party must comply with the provisions of 4.7.2. During the test, the mechanisms and parts of the machine must also be inspected according to the provisions of 4.7.3.
Noise
The noise level of the plate rolling machine is also an important aspect to be considered during the testing and inspection process. According to the guidelines, the power level of the noise sound of the plaque winding during the operation of the continuous air must not be greater than the provisions of the relevant technical documents.
Electrical System
The electrical system of the plate rolling machine must also be inspected according to the relevant provisions in GB/T 5226.1. This includes ensuring that all electrical components are properly installed and tested, and that the electrical system is functioning as intended.
Hydraulic and Lubrication System
The hydraulic and lubrication system of the plate rolling machine must also be inspected and tested to ensure that it is functioning as intended. According to the guidelines, the operating condition of the hydraulic system and lubrication of the rolling machine must comply with the provisions of 3.8.
Rigidity
The rigidity of the plate rolling machine must also be inspected and tested to ensure that it meets the required standards. According to the guidelines, the plate rolling machine must generally carry out load tests depending on the nominal rolling capacity, and a charger can also be used to form an additional equivalent on the actuator of the rolling machine.
Load Test
The load test is an essential part of the testing and inspection process. According to the guidelines, the plate rolling machine must generally carry out load tests depending on the nominal rolling capacity, and a charger can also be used to form an additional equivalent on the actuator of the rolling machine. The movements of all mechanism work systems during the test must be coordinated and reliable, and the number of load tests should not be less than three times and the simulation loading time should not be less than 0.5 h.
Precision Inspection
Finally, precision inspection is an essential step in the testing and inspection process. According to the guidelines, the accuracy of the rolling machine of the plate must be inspected after the load test, and the inspection is carried out. This includes ensuring that all measurements and dimensions are accurate and meet the required tolerances, and that all mechanisms and components are properly aligned and functioning as intended.
In conclusion, the testing and inspection of plate rolling machines is a comprehensive process that involves several critical steps to ensure the quality and precision of the machine. By following the guidelines outlined in this blog post, manufacturers and quality control inspectors can ensure that plate rolling machines are properly tested and inspected to meet the required standards and regulations.
